Detailed Description

The following describes a rack module, a connecting mechanism thereof and an unlocking element matching the connecting mechanism according to an embodiment of the invention. It should be appreciated, however, that the present embodiments provide many suitable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments disclosed are merely illustrative of specific ways to make and use the invention, and do not delimit the scope of the invention.

Unless defined otherwise, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

The foregoing and other technical and scientific aspects, features and utilities of the present invention will be apparent from the following detailed description of a preferred embodiment when read in conjunction with the accompanying drawings. Directional terms as referred to in the following examples, for example: up, down, left, right, front or rear, etc., are directions with reference to the attached drawings only. Accordingly, the directional terminology is used for purposes of illustration and is in no way limiting.

Referring to fig. 1 and 2, fig. 1 and 2 are exploded views of a stand module and a display device 10 at different viewing angles according to an embodiment of the present invention. As shown in fig. 1 and fig. 2, the display device 10 of the present embodiment is, for example, a liquid crystal display or an organic light emitting diode display, and mainly includes a main body 11 and a bottom cover 12, wherein the bottom cover 12 can be combined with the main body 11 to shield electronic components or connectors inside the main body 11.

It should be understood that, in order to fix the display device 10 on a wall or other supporting surface (such as a table or a floor), a bracket module is further disposed on the back side of the display device 10, wherein the bracket module mainly comprises a supporting element 20 and a connecting mechanism. The connecting mechanism includes a first member 30 and a second member 40. In the present embodiment, the supporting element 20 is fixed on a wall surface or other supporting surface, and includes a connecting portion 21 and a column structure 22, wherein the connecting portion 21 is disposed at an opposite top end of the column structure 22 and is used for connecting the second member 40. Further, the first member 30 and the second member 40 of the present embodiment can be separated from each other by an unlocking element 50 after being fastened to each other.

Referring to fig. 1 and 2, in an actual assembly process, the first member 30 may be fastened to the back side of the body 11 of the display device 10 by fasteners (e.g., screws), the second member 40 may be fastened to the connecting portion 21 of the supporting element 20 by fasteners (e.g., screws), and then the first member 30 and the second member 40 may be fastened to each other, so that the display device 10 can be fixed to a wall surface or other supporting surface (e.g., a desktop or a floor surface) by the bracket module. For example, the first member 30 and the second member 40 are made of plastic material.

Conversely, when the display device 10 is to be detached from the supporting element 20, the unlocking element 50 is simply inserted into the groove 32 of the first member 30 to release the first member 30 and the second member 40 from each other (disengage), and then the display device 10 together with the first member 30 can be slid out of the guide rail 41 of the second member 40 to facilitate the maintenance operation of the display device 10.

Next, referring to fig. 1 to 5, fig. 3 is a perspective view of the first member 30 shown in fig. 1 and 2, fig. 4 is a perspective view of the second member 40 shown in fig. 1 and 2, and fig. 5 is a perspective view of the first member 30 and the second member 40 shown in fig. 3 and 4 after being combined.

As shown in fig. 1 to 5, the first member 30 of the present embodiment has a long bar-shaped protrusion 31 and two grooves 32, the protrusion 31 has a wedge-shaped cross section, the grooves 32 are formed on the protrusion 31, and a rib 33 (fig. 3) is further formed between two adjacent grooves 32 on the protrusion 31; correspondingly, the second member 40 in this embodiment has a long-strip-shaped guide rail 41 and two cantilever structures 42, the guide rail 41 has a wedge-shaped cross section for accommodating the bump 31, the two cantilever structures 42 are respectively formed with a tail portion 421, and the tail portion 421 protrudes from the bottom side of the guide rail 41 toward the first member 30 after the second member 40 is engaged with the first member 30. In some embodiments, the number of the grooves 32 on the protrusion 31 of the first member 30 is not limited to two, and may be a plurality of designs including two or more, and of course, the cantilever structure 42 of the second member 40 may also be a plurality of designs including two or more. Specifically, the trenches 32 and the cantilever structures 42 are corresponding in number.

As can be seen from fig. 4, the second member 40 of the present embodiment is further formed with an elongated support structure 43 located between two adjacent cantilever structures 42, so as to improve the mechanical strength of the second member 40 as a whole.

It is further noted that, when the protrusion 31 of the first member 30 is inserted into the guide rail 41 of the second member 40 from top to bottom along the-Z-axis (first direction) to a combining position, the protrusion 31 will abut against a retaining wall 44 (as shown in fig. 1) on the second member 40, and the tail portions 421 of the two cantilever structures 42 will be respectively inserted into the two grooves 32 on the first member 30, thereby limiting the sliding of the first member 30 relative to the second member 40 along the Z-axis (second direction) to prevent the first member 30 from separating from the second member 40, wherein the second direction is opposite to the first direction. After the first member 30 and the second member 40 are engaged, an unlocking space S is formed between the groove 32 of the first member 30 and the cantilever structure 42 of the second member 40.

It should be noted that once the tail 421 of the cantilever structure 42 is inserted into the groove 32 of the bump 31, the first member 30 and the second member 40 are engaged with each other, and at this time, the first member 30 cannot slide in the Z-axis or-Z-axis direction relative to the second member 40; meanwhile, the first member 30 cannot slide in the X-axis or-X-axis direction relative to the second member 40 due to the design of the groove 32 and the rib 33 of the protrusion 31, so as to provide a limiting effect. In addition, the projection 31 of the first member 30 and the guide rail 41 of the second member 40 are designed by the complementary wedge-shaped cross sections thereof, so that the first member 30 cannot be disengaged in the Y-axis or-Y-axis direction with respect to the second member 40 to provide a clamping action.

As shown in fig. 1 and 2, the unlocking element 50 includes a main body 501, an extending portion 51 and an opening 52, the extending portion 51 is connected to the main body 501, and the opening 52 is located between the extending portions 51, so as to form a comb-like structure as a whole. In one embodiment, the number of the extending portions 51 is equal to the number of the grooves 32, and in this embodiment, the number of the extending portions 51 is illustrated as two, so that the comb structure of this embodiment is similar to an inverted U-shaped structure. In addition, when the unlocking element 50 is inserted into the unlocking space S along the-Z-axis direction (the first direction), that is, when the extending portion 51 of the unlocking element 50 enters the unlocking space S, the rib portion 33 of the first member 30 relatively enters the opening 52 of the unlocking element 50, and the tail portions 421 of the cantilever structures 42 of the second member 40 are respectively pressed by the extending portions 51 to be separated from the grooves 32, so that the first member 30 is in a slidable state relative to the second member 40 in the Z-axis direction (the second direction).

Referring to fig. 6 and 7, fig. 6 is a cross-sectional view of the stand module and the display device 10 before the first component 30 and the second component 40 are combined, and fig. 7 is a cross-sectional view of the stand module and the display device 10 after the first component 30 and the second component 40 are combined.

As shown in fig. 6 and 7, when the display device 10 and the first member 30 are combined with the second member 40, the bump 31 on the first member 30 is aligned with the guide rail 41 on the second member 40 along the vertical direction (fig. 6), and then the first member 30 and the display device 10 are moved along the-Z-axis direction (the first direction) so that the bump 31 of the first member 30 can smoothly enter the guide rail 41 of the second member 40 and reach the combining position (fig. 7), and the retaining wall 44 (shown in fig. 1) on the second member 40 interferes with the bump 31 to limit the bump 31 at the combining position.

It should be noted that, a limit structure 321 is formed at the end of the groove 32 of the first member 30, and during the process that the bump 31 is inserted into the guide rail 41 along the-Z axis direction (the first direction), the bump 31 will press the tail 421 of the cantilever structure 42 and deform the cantilever structure 42, and when the bump 31 is inserted into the groove 32 along the-Z axis direction (the first direction), the cantilever structure 42 can return by its own elastic force, so that the tail 421 is embedded into the limit structure 321 (fig. 7); at this time, when the first member 30 receives an external force in the Z-axis direction (second direction), the tail 421 of the cantilever structure 42 abuts against the limit structure 321 at the end of the groove 32 and is limited by the limit structure 321, so that the first member 30 cannot slide out of the second member 40, thereby greatly improving the safety in use and the convenience in assembly. In one embodiment, the tail 421 of the cantilever structure 42 has an L-shaped cross-section.

Referring to fig. 8 and 9 together, fig. 8 is a sectional view of the unlocking element 50 inserted into the groove 32 of the first member 30 along the-Z axis, and fig. 9 is a sectional view of the unlocking element 50 inserted into the groove 32 of the first member 30 and reaching the unlocking position.

As shown in fig. 8 and 9, when the display device 10 and the first member 30 are to be separated from the supporting element 20 and the second member 40 together, the unlocking element 50 can be held by hand and inserted into the unlocking space S between the groove 32 and the cantilever structure 42 along the-Z axis direction (the first direction) (fig. 8), and when the unlocking element 50 is inserted to reach an unlocking position in the groove 32 (fig. 9), the two extending portions 51 of the unlocking element 50 respectively press the tail portion 421 of the cantilever structure 42, and the tail portion 421 of the cantilever structure 42 is separated from the groove 32 of the first member 30, specifically, from the limiting structure 321 of the groove 32 of the first member 30.

In this way, the first member 30 and the second member 40 can be released (disengaged) from each other, so that the display device 10 can be drawn out from the guide rail 41 of the second member 40 together with the first member 30, thereby facilitating the subsequent maintenance operation of the display device 10.

Referring next to fig. 10, fig. 10 is a perspective view of the unlocking element 50 inserted into the groove 32 of the first member 30 along the-Z-axis direction. As shown in fig. 10, when the unlocking element 50 is inserted into the groove 32 of the first member 30 in the-Z-axis direction (the first direction) (i.e., the unlocking space S shown in fig. 8 and 9), the two extending portions 51 of the unlocking element 50 enter the two grooves 32 of the projection 30, and the rib 33 located at the center of the projection 31 enters the opening 52 of the unlocking element 50.

In summary, the first member 30 and the second member 40 are respectively provided with the corresponding protrusion 31 and the corresponding guide rail 41, and the cantilever structure 42 (the elastic arm) is engaged with the groove 32, so that the connection mechanism is effectively prevented from being touched by mistake to cause the first member 30 and the second member 40 to be loosened. On the other hand, the unlocking element 50 of the present invention adopts a comb-shaped special structure design, so that the present invention is not only convenient to use, but also has an anti-theft function due to the special shape and the difficulty in imitation, thereby greatly improving the convenience of the bracket module in disassembly and assembly and the safety in use.
